Squogres
The Sqougers were named by Jesse inside the treehouse in Terabithia. It is depicted as a creature that's half-squirrel half-ogre. After Leslie told him its Scott Hoager, he replies with "a Squogre". The Squogers are enemies Jesse and Leslie use to combat Scott Hoager, a bully from the Lark Creek Elementary school. Once Jesse punched him in the face because of his callous remark about Leslie's death, the Squogers vanished.
The Squogers mimic the beep of Scott Hoager's 'loser detector'.
